Solve this system of equations using substitution
y = - 4
x + 2y = 10
Step 1: Substitute for y in the second equation. Which is
the resulting equation?

x + 2(-4) = 10

x - 8 = 10

x = -18

y = -4

(-18, -4)

Step-by-step explanation:

x + 2(-4) = 10

Step-by-step explanation:

Substituting -4 for y in the second equation results in x + 2(-4) = 10.  This simplifies to x - 8 = 10 and then x = 18.
